Deep Hole Drilling Speed and Feed Adjustment Holder Length

Recommended Speed and Feed Example

E

If the recommended speed and feed is 200 SFM and 0.008 IPR for a stan dard length holder, then the speed and feed using a 3XL holder in the same application would be 150 SFM and 0.007 IPR.

Tool failure can cause serious injury. To prevent: - When using holders without support bushing, use a short T-A® holder to establish an initial hole that is a minimum of 2 diameters deep. - Do not rotate tool holder more than 50 RPM unless it is engaged with the workpiece or fixture. Visit www.alliedmachine.com/DeepHoleGuidelines for the most up-to-date information and procedures. Factory technical assistance is available for your specific applications through our Application Engineering Team. WARNING

SPECIALS

IMPORTANT: The speeds and feeds listed above are a general starting point for all applications. Refer to the Coolant Recommendation charts for coolant requirements to run at the recommended speeds and feeds. Factory technical assistance is available through our Application Engineering department. See adjustment examples on the following page.
